Fish feed and preparation method thereof

Abstract

The invention relates to the technical field of fish feed preparation, in particular to fish feed and a preparation method thereof. The proportional design is performed through fermented cow mature, corn, wheat bran, common salt, mineral supplements, sodium bicarbonate and fermented pasture, so that the mixture ratio of all raw materials is reasonable; the nutrition structures can be mutually improved; particularly, the palatability of fermented cow manure can be improved; the eating quantity of the feed fed for feeding the fish is increased; the bringing of harmful pathogenic bacteria is avoided; the culture risk is prevented; the safety coefficient is improved.

Description

technical field

[0001] The invention relates to the technical field of fish feed production, in particular to a fish feed and a preparation method thereof. Background technique

[0002] As the feed for fish farming, raw bait (fresh or frozen horse mackerel, mackerel, sardine, sand eel, squid, etc.) that is also consumed as bait in nature comes to mind first. Raw bait is the original natural bait of fish, so it is excellent in terms of fish preference and nutritional benefits of fish, but raw bait suffers from many problems such as stable supply and stable product quality because it is derived from natural resources. Wet pellets obtained by blending vitamins, minerals, natural starch, etc. Particulates can cause environmental pollution problems.

[0003] In recent years, the rapid development of the aquaculture industry, especially the relatively rapid development of the fish farming industry, has led a large number of researchers to start researching on fish feed, some of ...
